WATER-HEATlNG FIREHGRATE.

SPECIFICATION forming part of Letters Patent No. 582,023, dated May 4,1897. Application filed August 26, 1896. Serial No. 603,989. (No model)To all whom t may concern.-

Be it known that we, JOHN H. PHILLIPS and GEORGE H. GERBER, citizens ofthe United States, residing at Pottsville, in the county of Schuylkilland State of Pennsylvania, have invented certain new and useful Improvements in VVater-Heating Fire-Grates; and we do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

Our invention relates to furnaces or lireboxes of heating devices, hasfor its object improvements on the patent to John H. Phillips, datedOctober 30, 1894, and numbered 528,388, and consists in certainimprovements in construction, which will be fully disclosed in thevfollowing specification and claims.

In the accompanying drawings, which form part of this specification,Figure l represents a vertical section, partly in elevation, of ourinvention; Fig. 2, a top plan View on the line 2 2, Fig. l; and Fig. 3,a front elevation ofthe fire-pot detached. 4 p

For the purpose of illustrating we have shown our invention applied tothe fire-box or fuel-chamber of a domestic stove, such as a kitchenrange or cooking-stove, but it may be applied to other heatingapparatus.

Reference being had to the drawings and the letters thereon, A indicatesthe furnace or {ire-box for containing fuel; B, the combustion-chamber,which in the illustration of its use is above and directly over the ovenC of a range. or cooking-stove, and D the stack or stove-pipe.

In the fire-box or fuel-chamber A is placed the water-heating fire-pot,made in two separate sections or pockets E F, constructed of coiled pipeand made to fit the fuel-chamber, each section occupying one-halfthereof and providing two adjacent ends ab, which cross the fuel-chambertransversely and are embedded in the fuel, while the spaces between saidends and between the coils afford ingress for air to supply oxygen tothe fuel in the center and throughout the depth of the fuel in thefuel-chamber.

On the front, back, and outer ends of the section is supported above thebottom f of the combustion-chamber by any suitable means to allow theproducts of combustion to envelop the pipe of the section whichtraverses the combustion-chamber from end to end, as shown, or from sideto side, if desired, but the former construction is preferred, as it en*ables the combustion-chamber to be cleaned readily by moving the ashesfrom between and under thecoils of pipe toward the fuelchamber.

The section G extends throughout the combustion-cllamber and greatlyaugments the heating capacity of the fire-pot. From the section G asection H may be extended into the stack or pipe D to still furtherincrease the heating capacity, and to the upper end of the section Dapipe g may be connected to conduct the hot water or steam to any desiredplace for use.

I indicates a tank designed to be placed outside the building, or in anypreferred place,

and is connected with the fire-pot by pipes h,

communicating with the section H, and 7c, communicating with the lowerends of the sections E F, respectively, and water is supplied to theiire-pot through pipes t' 7s, with which the pipes t' 71: alsocommunicate to maintain circulation.

As constructed, either of the sections E F may be used separately oreither may be removed for repairs or renewal without disturbing theother, or they may be used together.

The water-tank I may be provided with suitable pipesfor conducting waterto any desired place for use and with suitable pipes for drawing off thewater and accumulated sediment,

all of which is within the skill of the artisan and requires noillustration or further elucidation.

Having thus fully described our invention, what we claim is- 1. Awater-heating fire-pot having two independent and adjacent pockets, thesaid pockets being formed of coiled and continuous piping.

2. A water-heating re-pot having two independent and adjacent pockets,the said pockets being formed of coiled and continuous pipingand thepockets and the convolutions of the coils being spaced so as to permitthe iow of air between them.

A wate1-heating fire-pot having two independent and adjacent pockets,the said pockets being' formed of coiled and continuous piping and thepockets and the convolutions of the coils being spaced so as to permitthe flow of air between them, in combination with a section of pipetraversing the combustionchamber and connected with the pipes of bothpockets of the fire-pot.

In testimony whereof we affix our signatures in presence of twowitnesses.
